07 yz not running correctly help please

recently replaced jets, AP diaghram, aftermarket fuel mixture screw. It is being a pain to start.... and when it gets warmed up and taken off choke it sounds like the choke is still on.. idles high, but once you start to ease off the clutch...rpms drop back to normal. With the rpms high, i can pull the hotstart and it does idle a little higher,,, before i take evrything apart to get to the hot start just curious if i am missing something else.

since you didnt put what year your bike is, hard to say if you have the correct fuel screw or not.

and also could be an air leak of some sort.

I put the year in the title. It is a 07. Where would be the best places to check for an air leak

where do you think air could leak in and change how the motor runs?

Im trying to help A friend get back on 2 wheels

Check the intake boot between the carb and head. You can use carb cleaner while the engine is running. If you hear the RPMs change then you have a leak. Also check the hot start. Sometimes they get stuck a little open
